It is important in the generation of Rossby waves. The Rossby parameter $\backslash beta$ is given by〔(Glossary of Meteorology ), American Meteorological Society.〕〔(Lecture Notes ) for Atmospheric Science Mesoscale Dynamics (MEA 713). North Carolina State University. Accessed 14 July 2007.〕 :$\backslash beta\; =\; \backslash frac\; =\; \backslash frac\; \backslash frac\; (2\; \backslash omega\; sin\backslash phi)\; =\; \backslash frac$ where $f$ is the Coriolis parameter, $\backslash phi$ is the latitude, $\backslash omega$ is the angular speed of the Earth's rotation, and $a$ is the mean radius of the Earth. Although both involve Coriolis effects, the Rossby parameter describes the ''variation'' of the effects with latitude (hence the latitudinal derivative), and should not be confused with the Rossby number. ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rossby parameter」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
